C5 Battery Disconnect

[Dircon]

Hello Guys.

2001. C5 Exclusive SE V6 Auto.

I really hoped that someone here would have had some info' as to how to route an Aux' Input from the back of the Radio to outside the Front Fascia. Preferably, via the Ashtray, which sits beneath the Climate Controls, and in front of the Gear Lever.

However, it appears that nobody here has any knowledge of fitting an Aux' Input.

So, I am just going to have to carry on regardless, and attempt to fit my new Connect2 Aux' Input.

What I do hope you can help me with now is:

Obviously, in order to fit the Aux' Input I will need to remove the Radio. I have already, (due to previous jobs undertaken), needed to twice Disconnect the Battery. I then followed the BSI Reset procedure. I don't really want to do it again just yet.

So, finally my question: Is it essential to Disconnect the Battery in order to Temporarily remove the Radio?


Any help with this Battery question, or with the Aux Cable Routing would be very welcome.

Many thanks,
Paul

No its not necessary its just sensible, you risk blowing fuses or even starting a fire under the dash. For the small amount of effort required why would you risk it?

If you just need to get to the back of the radio, then you could pull the radio out and leave it connected up and then no need to bother about the battery. I had to do this when removing the ashtray to repair it.

 

If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3:

- remove the ignition key from the car

- open the bonnet

- wait a few minutes for the BSI to shut down

- disconnect the battery negative terminal

 

When reconnecting

- ignition key out of the car

- reconnect the battery

- wait a few minutes

- insert the key in the ignition and wait a minute

- turn the key to the first position and wait a minute

- turn the key so the dash lights come on and wait a minute

- start the engine

- take the windows down and up to reset the anti pinch

- reset the clock (and radio on the C3).

 

As for routing a cable, once you know where you want to end up, by removing the gear lever gaiter, you may be able to push a wire through with a rod towards the front and reach behind the back of the dash to feed it to the radio area.
